Fish Identification Guide

White Perch
Morone americana
Illustrations by Joe Tomelleri
Description: A silvery, flat bodied fish with 3 anal fin spines that are not stair-stepped (second and third anal spine length nearly equal); sides nearly plain or may have faint stripes; 2 dorsal fins that are slightly connected; and no teeth on base of tongue. It is a non-native, temperate bass that has become established in several reservoirs as well as streams, rivers, and associated flood plain waters. Once it becomes established, it has a tendency to become overpopulated and stunt if there are not sufficient predators present. It is a schooling fish and primarily feeds on microcrustaceans (small zooplankton), immature aquatic insects, crayfish, small fish, and fish eggs.
Note: This fish species can be very harmful for the state's aquatic resources. If you are confident that you captured or observed this fish, contact the nearest NGPC Fisheries personnel or the Commission's Private Waters Specialist at (402) 471-5435 and report where it was found (name of the lake, stream, river, sandpit, etc.), a legal description for the location (section, township, range) and date. Also include your name and phone number for a followup investigation.
